I have a set CV's on my car from The Driveshaft Shop. They are based on Porsche 930 CV's so very similar to the VW ones from other kits, just larger. They have been awesome (no play, fit well, etc) apart from one problem. I have had to replace at least 3 boots since I purchased them. I think the reason for the failures I have had is the same reason for other failures that people are experiencing: excessive angularity.

Many people switch to CV's because their cars are so low the excessive angularity on the half shafts is causing u-joint related vibrations and failures. While the CV's will help with this, they still do not like to be run at extreme angles. Production car CV's can last so long because they typically do not operate at extreme angles. Lifted trucks run into the same angularity issues that we have and you regularly hear about CV failures in truck/offroad circles.

So maybe we all need to go to a more sensible ride height...(yeah right, like that's going to happen)

I never blamed Troy for anything nor should you, as I believe my CV failure being One CV, was due to one of two things as I mentioned originally.

1. I may have has something between the CV boot to CV that did not allow a good seal, and like I originally said, I doubt that because I made damn sure all surfaces were clean clean clean.

2. Boot seal to CV was fugazi to begin with so, oh and his adapters are pretty much what you and Futofab sell besides Troy has already redesigned his adapters with a zirk fitting so you can add grease

I STILL haven't taken that CV off the axle yet because I'm fixing the 510's boo boo but will soon enough and let you all know what I find.

I am NOT blaming Troy at all because I don't believe it to be anything but One of those things, just because it's new don't mean Toro De Caca. But I will find out why grease leaked from One and only one.

Actually I responded to Matt's "Looks like Troy needs to redesign the adapters for containing the grease" if this isn't saying "Blaming" Troy's adapters when my issue was grease escaping and ruining a Single CV, then I don't know what is. Not here to start arguments guys, I just don't want Troy thinking I'm blaming him when I'm pretty sure it's the boot ring seal against the CV not the adapters. Remember, only one of four leaked. If it were the adapters im pretty sure they all would have leaked and I wouldn't be the only one reporting such a thing.

Well I will assure you that my comment is not blaming Troy. As you have only used a portion of the comment, and assigned a pile of conjecture to it.

Conjecture = " if this isn't saying "Blaming" Troy's adapters when my issue was grease escaping and ruining a Single CV, then I don't know what is."

The remainder of my comment also spoke of me redesigning my own adapter design as well. So no, it isnt blaming anyone. It is a general comment of improvement to an existing product.

I take offense because of your assumption. You even bypass people who actually claim they would never buy his product again.....Yet use a partial quote to take a swipe at me as if I blame him?

Your original post and following few do enough to blame Troy rather than cherry picking my comment for whatever reason.

Just to be clear on my comment that I would not buy it again. No grease escaped from my CV's. The problem I have with them were the tolerances in the splines and the rest of the machined parts. Having 5+ degrees of rotation in parts because of crappy tolerances is my problem. Mine show that they have had some heat also even with being fully packed with grease.

If no one from the future comes back to stop you from doing it then how bad of a decision can it really be?
